Nice catch. Sounds indeed more reasonable than the issue about
ovirt_host_facts (which is real, but still not failing us).

Are you sure? Can you check with ps if the qemu process is still up?
If so, you can try to ssh to it. IIUC you are still in the first stage
of deploy, where the VM is on the local network. You should be able to
find its IP address in the ansible logs, search for "local_vm_ip".

If it's dead: it might be that your engine tried to connect to the
host to an IP address it can't reach, either due to name resolution or
due to routing/firewalling etc. Both cockpit and the CLI ask you about
adding entries to /etc/hosts on the engine VM. Did you reply 'Yes'?

As I said previously in this thread, this is indeed a bug. Please open
one, and attach all relevant logs, versions of packages, repos used to
install them, etc. Thanks!

That said, it did not happen for me, for some reason. I got e.g. this,
in bootstrap_local_vm log:

2019-12-22 10:31:29,411+0200 DEBUG var changed: host "localhost" var
"host_result_up_check" type "" value: "{

"ovirt_hosts": [

"deprecations": [
{
"msg": "The 'ovirt_host_facts' module has been renamed to
'ovirt_host_info', and the renamed one no longer returns
ansible_facts",
"version": "2.13"
}
],
"failed": false
}"

I also see the same for latest nightly 4.3 CI test:

https://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-4.3/301/

https://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-4.3/301/artifact/exported-artifacts/test_logs/he-basic-suite-4.3/post-012_local_maintenance_sdk.py/lago-he-basic-suite-4-3-host-0/_var_log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-ansible-bootstrap_local_vm-20191230212741-a7v9pn.log

This should be ok.

I am not aware of a fix yet. One should probably not be that hard to
prepare, but I need to first reproduce. I wonder if your (and others')
problem is elsewhere.

[ovirt-users] Re: Issue deploying self hosted engine on new install

[Sang Un Ahn]

Hi,

I have figured it out that the root cause of the deployment failure is timing 
out while the hosted engine was trying to connect to host vis SSH as shown in 
engine.log (located in 
/var/log/ovirt-hosted-engine-setup/engine-logs-2019-12-31T06:34:38Z/ovirt-engine):

The FQDN of hosted engine (alice-ovirt-engine.sdfarm.kr 
) is resolved as well as the host 
(alice-ovirt-01.sdfarm.kr ) and SSH is the 
one of services that are allowed by firewalld. I believe the rules of firewalld 
is automatically configured during the deployment to work with hosted engine 
and the host. Also root access is configured to be allowed at the first stage 
of deployment. 

I was just wondering how I can verify the hosted engine can access to the host 
at this stage? Once it fails to deploy, the deployment script make all things 
rolled back (I believe it cleans all up) and the vm-status of hosted-engine is 
un-deployed. 

Thank you in advance,

Hi,

Most probably it is a bug.
Can you add 'debugger: on_failed' to the  task  ?

Maybe it will provide  a hint where is the issue.

[ovirt-users] Re: Issue deploying self hosted engine on new install

Hi, 

I have encountered the same error that results in the failure of hosted engine 
deployment. I have tried to replace "ovirt_host_facts" by "ovirt_host_info" in 
/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/bootstrap_local_vm/05_add_host.yml
 however it did not help with the following error message:

And one of the requirements to use "ovirt_host_info" is

I have been trying to install the latest oVirt (based in 4.3 repository) and 
hyperconverged mode using 3 nodes. Tried already with cockpit installation and 
now debugging it by using CLI installation. 

Is this a bug or is there already a fix?

I just wish oVirt's documentation was a little more clear and especially a

it would seem that 4.3.x of oVirt is not compatible with any version of

Hi Robert,

I'm just speculating, but maybe the package on the oVirt is too new or too old ?

What version is your Foreman ?

Have you tried to downgrade/upgrade the packages for the integration between 
the 2 systems ?

So I just setup a brand new Foreman instance and have been trying to get it

have the oVirt engine setup as a computer resource.



Where I am running into an issue is adding Foreman as an additional provider 
under oVirt.



In the log I get:

Any thoughts?

[ovirt-users] Re: what is "use host" field in storage domain creation??

[Strahil]

I think SPM is not doing initial setup - just other tasks - like snapshots 
creation/deletion.

isn't it SPM's job?
and is the "use host" required only for setup?

[Benny Zlotnik]

One host has to connect and setup the storage (mount the path, create
the files, etc) so you are given the choice which host to use for this

[ovirt-users] what is "use host" field in storage domain creation??

[hyunooudy]

hello and happy new year~

I am wondering role of "use host" field in storage domain creation.

https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage.html
above link says all communication to the storage domain is through "use host".
but I can't understand inefficiently passing through that "use host" even 
though every host can directly access to all domains.

it seems like i am misunderstanding something.
